Passage: 'Tsar Bomba (Russian: Царь-бомба; 'Tsar-bomb') was the Western nickname for the Soviet RDS-220 hydrogen bomb (code name Ivan or Vanya), the most powerful nuclear weapon ever detonated. Its test on 30 October 1961 remains the most powerful man-made explosion in history. It was also referred to as Kuzkina mat (Russian: Кузькина мать; 'Kuzma's mother'), possibly referring to Nikita Khrushchev's promise to show the United States a Kuzkina mat (an idiom roughly translating to 'We'll show you!') at a 1960 session of United Nations General Assembly.'. Question: 'who has the strongest nuclear bomb in the world'.
